Your Reliable Marine Navigation Dashboard Transform your iPhone or iPad into a dependable marine instrument display. NMEASail securely connects to your yacht’s network via NMEA 0183 or SignalK, delivering essential cruising data straight to your hands in real-time. NMEASail displays your most important navigation data on your iPhone or iPad, wherever you are on your boat. Whether you are navigating an offshore passage, fine-tuning your sail trim, or keeping an eye on surrounding traffic through the fog, NMEASail delivers precision engineering wrapped in a clean, legible interface built for the marine environment. KEY FEATURES Universal Network Connectivity Plug and Play: Connect dependably to onboard WiFi multiplexers or networking gateways. NMEA 0183 and SignalK: Full support for legacy NMEA via TCP/UDP alongside modern JSON data streams over SignalK WebSockets. Auto-Discovery: Easily locate and link your connection ports using the built-in Subnet Scanner which safely identifies broadcasting marine networks. Augmented Reality (AR) Navigation See Through the Fog: NMEASail’s AR camera overlay projects AIS targets and compass alignments against the physical horizon. Offline OpenSeaMap Integration Marine Charts Anywhere: Access dependable depth contours, seamarks, and buoys overlaid securely on top of Native Maps. Aggressive Caching: Browse your local sailing area while connected to the internet, and NMEASail will proactively cache the marine tiles for confident offshore, zero-signal navigation. Vessel Tracking: Keep track of your path drawn smoothly across the chart, accompanied by a responsive radar-style compass scale. Live AIS Tracking Identify surrounding vessels directly on your dashboard Map or through the AR lens. Retrieve instant details such as a target’s Ship Name, MMSI, Speed, and Course. Filter targets radially up to 40 NM to minimize distraction in heavily congested shipping lanes. Custom Yacht Polar Diagrams Optimize Your Output: Import vessel-specific .txt or .csv polar curve telemetry directly into the application. NMEASail processes these values into an interactive 3D table, applying accurate target speeds directly to your gauges to indicate real-time performance relative to your current wind angle. Analog Instruments Highly Legible Gauges: Crisp, meticulously designed analog dials measuring Wind Speed, Apparent/True Wind Angles, and Speed Over Ground. Magnified Wind View: An intuitive pinch-to-zoom gesture on the wind dial isolates the close-hauled sector, granting the helmsman uncompromising steering resolution. Simple Configuration: Tap any instrument face to cycle seamlessly between preferred measurement units (knots, km/h, m/s). Day and Night Themes Preserve your night vision on evening passages. Switch effortlessly between four distinct aesthetics: Dark, Solaris Light, Neon, and Dark Neon. The interface dynamically rebuilds to ensure deep contrast and legibility, functioning perfectly under glaring midday sun or pitch-black shifts.
